WebDerivation of second law of motion Solution Suppose an object of mass, m is moving along a straight line with an initial velocity, u. It is uniformly accelerated to velocity, v in time, t by the application of a constant force, F throughout the time, t. The initial and final momentum of the object will be, p1 = mu and p2 = mv respectively. WebFeb 6, 2024 · Newton’s second law of motion is only applicable for an inertial frame. The formula to ponder on for Newton’s second law of motion is F = ma [where F=external force, m=mass, a=acceleration] As of Newton's second law, external force on a body is equal to the rate of change of momentum of a body. Momentum is a vector quantity.

WebWelcome to Class 9 force and laws of Motion Notes for Chapter 9.The topics in this page are balanced and unbalanced forces ,Laws of motion,First law of motion, Momentum, Second Law of motion ,Third Law of motion and Momentum Conservation.This is according to CBSE and the NCERT textbook. If you like the study material, feel free to … Newton’s second law states that the acceleration of an object depends upon two variables – the net force acting on the object and the mass of the object. The acceleration of the body is directly proportional to the net force acting on the body and inversely proportional to the mass of the body. This means … See more When we kick a ball, we exert force in a specific direction. The stronger the ball is kicked, the stronger the force we put on it and the further away … See more It is easier to push an empty cart in a supermarket than a loaded one, and more mass requires more acceleration. See more Among the two people walking, if one is heavier than the other, the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.

WebMar 16, 2024 · Second Equation of Motion Last updated at March 1, 2024 by Teachoo it is denoted by s = ut + ½ at 2 Distance=Initial Velocity × Time + 1/2acceleration × time 2 Where s = Distance Travelled u = Initial Velocity t = time taken a = acceleration How is this Equation Derived? Questions WebAug 28, 2024 · Answer: Since the velocity at the highest point is zero, so the momentum of the object is zero at the highest point. Question 7. State action and reaction when a bullet is fired from the gun. Answer: Action: Force exerted by a spring on the bullet. Reaction: Force exerted on the gun. Question 8. WebMay 19, 2024 · Newton's Second Law of Motion It states that the rate of change of momentum of a body is directly proportional to the applied force and takes place in the direction in which the force acts.... sidney griffith
